Air conditioning management device and program
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing building management systems for air-conditioning management lack commonality in screen display capabilities between man-machine devices and terminal devices, leading to increased development and maintenance costs, and reduced visibility and operability.
Innovation Solution
An air-conditioning management device that includes display means, terminal communication means, storage means, and management screen generation means, which synthesizes air-conditioner data with web content data to generate a management screen with a layout similar to a general web browser, excluding specific display fields, thereby reducing development costs and enhancing visibility and operability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a dedicated man-machine device with proprietary screen display capabilities is used for air-conditioning management, then the device can provide specialized control functions, but development and maintenance costs increase due to lack of commonality with terminal devices
Solution Approach 1:
The air-conditioning management device enables the man-machine device to generate and display management screens using the same web content data that terminal devices use, making the screen display capability universal across different device types. This allows one system to serve multiple functions (specialized control and general web browsing) without requiring separate proprietary display systems.
Solution Approach 2:
The management screen generation unit creates management screens by copying and synthesizing web content data stored in the storage unit, rather than using proprietary display templates. This copying approach allows the man-machine device to reuse existing web content, reducing development costs while maintaining specialized control capabilities.
2Ease of repair
If a proprietary display system is implemented in the air-conditioning management device, then specialized control functions are achieved, but maintenance costs increase due to separate system management
Solution Approach 1:
By making the screen display system universal (using shared web content data), the patent reduces system complexity. The same web content data serves both terminal devices and the man-machine device, eliminating the need to maintain separate proprietary display systems and reducing maintenance burden.
Solution Approach 2:
The patent merges the display systems by having the man-machine device use the same web content data storage and screen generation approach as terminal devices. This consolidation reduces maintenance costs by eliminating duplicate system management while preserving specialized control through the management screen generation unit.
3Ease of operation
If web content data is displayed in full browser layout format, then commonality with terminal devices is achieved, but visibility and operability are reduced due to unnecessary display fields
Solution Approach 1:
The management screen generation unit applies local quality by selectively displaying only relevant portions of web content data on the management screen. It excludes unnecessary display fields (such as address bars, toolbars, and other browser interface elements) while preserving essential air-conditioning control information, thereby improving visibility and operability.
Solution Approach 2:
The patent extracts and displays only the essential management information from the web content data, removing unnecessary browser interface elements. This extraction process creates a streamlined management screen that maintains commonality with terminal devices while improving operational efficiency by eliminating distracting or irrelevant display fields.

AI summary
An air-conditioning management device (2) includes a data storage (24) that stores web content data (241) and air-conditioner data (240) relating to an air conditioner. A web server (251) transmits, in response to a request from a terminal device, the web content data (241) via a terminal communicator (23) to the terminal device. A management screen generator (252) generates a management screen for management of operating states of the air conditioner by synthesizing the air-conditioner data (240) with screen data that is based on the web content data (241), and outputs the generated management screen to a display (20).
